IMPROVEMENT IN PUMPS.

To all whom it may concern.- Y

Be it known that I, ELIils RHoADEs, Sr., of Clyde, in the county ofSandusky and State of Ohio, have invented new and useful Improvements inPumps; and I do hereby declare that the following is a full and completedescription of the construction of the same, reference being had to theaccompanying drawings, making part of this specification, in which-Figure 1 is a perspective view. Fig. 2 is a vertical section, and Figs.3, et, and 5 are detached portions.' V The nature of my inventionrelates to such a construction of a pump that any movement of the pistoncauses a Bow of water through the exit-pipe, said pipe being connectedto the piston-head and forming the rod by which it is actuated; also tothe valves by which the water is admitted into the pump-cylinder, and tothe arrangement of the valves in the piston-head.

A in Figs. 1 and 2 represents the barrel or cylinder of the pump. Thelength thereof may be six or more inches, and the diameter three or moreinches, according to the intended use. It may be made of sheet metal orcast-iron and bored out smoothly inside.

a a, Fig. 2, shows a narrow rim projecting inward at each end of thecylinder A, which forms a seat for the valves hereinafter to bedescribed.

B B represent heads attached to the ends of the cylinder, leaving aspace of about threequarters of an inch between the ledge a and the headB. -Both heads have a circle of holes,`O, near the outer margin throughwhich the water passes into the barrel of the pump.4

Between the heads B and ledges a is interposed the disk-valves D, whichconsist of a thin plate of metal, perforated with a number of holes, O,equal to those in the heads B, but placed upon a smaller circle, so thatwhen the valve in either rests against the head the holes O are closedby the outer margin of the valves D. This feature is clearly shown inFigs. 4 and 5. v

So far as the two heads and disk-valves are concerned, their structureand operation is alike.

E represents the piston-head or plunger. It consists of a broad ring, F,which accurately lits the inside of the barrel A, and a doublediaphragm, e e, having their convex sides in contact at the center,their outer edges separated about one-third the width of the ringF andsecuredin two lines around the inside. The diaphragms thus mutuallybrace each other. The diaphragm is perforated at the center,as seen atn, for a passage ofthe water upward when the piston descends. Thisopening is provided with flap-valves m m, which close the opening 'nwhen the piston-head rises, and open upward when the piston head falls.

G represents the piston-rod. This is made hollow, and' therefore servesthe double purpose of piston-rod and conducting pipe. It passes throughthe upper head and upper diskvalve, through the opening H, Fig. 5. Thelower end of the pipe G,where it joins the diaphragm, expands, as seenat I I in Fig. 3, and is provided with openings yo o for the purpose ofadmitting the water from the upper chamber of the cylinder A. Theseopenings o o are closed by the Ilapvalves in m when the piston descends.v

L is a lever by which the piston is operated. This has as tationaryfulcrum, N, and the short arm is attached to the piston-rod by anarticulating-joint, N. The upper end of the hollow piston G is turneddownward forming a water. The cylinder of the pump is secured in thewater, so that the whole is submerged, and at every downward strokethewater in the lower chamber, P, passes through the valves m and isdischarged above, and the chamber IJ' is iilled at the same time by thefalling of the upper disk-valve, D, and at every upward stroke of thepiston the lower chamber P. v

What I claim as my improvement, and desire to secure by LettersvPatent,is

The disk-valves D, perforated heads B, and ledges a, in combination withthe hollow pistonrod G, and valves m, and openings o, when these severalparts are constructed, arranged, and operated in connection with thecylinder A, as and for the purpose specified.
